The three consecutive odd numbers are x, x+2, x+4
add up: x+x+2+x+4=255
3x+6=255
3x=249
x=83
83, 85, 87
Answer:
first option
Step-by-step explanation:
Given
| x + 4 | = 2
The absolute value function always produces a positive value but the expression inside can be positive or negative, thus
x + 4 = 2 ( subtract 4 from both sides )
x = - 2
OR
- (x + 4) = 2, distribute left side
- x - 4 = 2 ( add 4 to both sides )
- x = 6 ( multiply both sides by - 1 )
x = - 6
Thus solutions are x = - 2, x = - 6
These are represented on the graph by solid blue circles at x = - 2, x = - 6
The first option represents the solution
Answer:
(x+1)(x+9)
Step-by-step explanation:
using ac method
so there are 2 x so each go in a ( ) then you have to do the box method and get 9 at the right corner at the end. then get your 2 like terms combined then boom you got your answer.
Answer:
B
Step-by-step explanation:
Angle ABD is congruent to angle CBD--->Definition of perpendicular lines
Segment DB is congruent to Segment Db--->Reflextive property of congruence
Angle ADB is congruent to angle CDB--->angle bisector theorem
2 angles and 1 side is congruent, therefore <em><u>the triangles are congruent by the ASA Congruence Theorem</u></em>
Using empirical rule,
Upper range of 68%=15+5=20
Lower range =10
Range=10
